August 2000: The list of reference plants now boasts the largest plant for the production of 120,000 l/hr pure alcohol ever built by GEA Wiegand.
The plant purifies raw alcohol of different origin and quality into neutral or fine alcohol which considerably surpasses the usual sensory and analytic specifications. At the same time, rectified alcohol is dehydrated in an energetically connected system, which means that no additional steam is required for this process. In total, the plant has a consumption of less than 1.5 kg steam per litre of pure alcohol.
Depending on the quality of the raw alcohol, the losses of alcohol yield amount to a few percent. The cooling water consumption is reduced to a minimum thanks to the use of air coolers.
